MANTLE-SUPPORTI SPECIFICATION forming part of Letters Patent No. 696,492, dated April 1, 1902. Application iiled August 19, 1901. Serial No. 72,509. (No model.)

To all whom it may concern:

Be it known that I, JACOB I. ROBIN, a citizen of the United States, residing in Mount Vernon,Westchester county, and State of New York, have invented certain new and useful Improvements in Mantle-Supports, of which the following is a specification.

My invention relates to a support for the mantle employed in an incandescent gaslamp; and the object of my invention is to provide such supports with means to take up vibrations, particularly lateral vibrations, and to facilitate the placing in position a mantle'over the burner-cap of a gas-lamp.

I will describe a support embodying my invention and then point out the novel features thereof in a claim.

In the accompanying drawings, Figure 1 is a View in elevation of a burner-cap, mantle, and mantle-support, the latter embodying my invention. Fig. 2 is a view partly in elevation and partly in vertical section.

Similar letters of reference designate corresponding parts in both of the figures.

A represents the usual form of burner-cap employed in incandescent gas-lamp. These Caps, as is well known, are detachable from the lamp. A' represents a bracket fixed to said cap.

B represents a mantle-support which, as here shown, comprises a vertical rod Z), a spring b', to which one end of the rod b is connected, and a fixed part b2, also connected to the spring. The part b2 is U-shaped, one

leg of the U being somewhat shorter than the other. The longer leg of the U is iixedly held and extends downwardly in the bracket A therefrom.

One end of the spring b is 'fixed to the short leg of the U, and one end of the part b is secured to the other end of the spring' and directly above the short leg of the U. The other end of the rod Z2 is provided with the usual hook to receive the asbestos loop of the mantle C. With this construction of support the spring b' is entirely out of the heat zone of the lamp-burner, and consequently its temper will not be affected. The provision of a separate spring between two rigid parts of the support will allow of one part being moved relatively to the other much more so than would be the case if the spring was a part of the support. Vith this construction of support also the mantle O can be easily placed in position. It is only necessary to move the part b outwardly, place the mantle on its end, and then allow the part b to come back to its normal position. This operation is clearly shown in dotted lines in Fig. 2.

What I claim as my invention is- The combination of a burner-cap of an incandescent gas-lamp, and a support for the mantle thereof, said support comprising a U-shaped part having one end fixed to said cap, a spring secured at one of its ends to the other end of the fixed part, and a second part for suspending the mantle at one end thereof, and having its other end connected with the other end of the spring.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

JACOB I. ROBIN.
